What are the differences between the surface processing of spiral steel pipe and stainless steel pipe
Let’s first talk about the original surface of the stainless steel pipe: NO.1 The surface that is heat treated and pickled after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industry equipment, etc., with thicker thicknesses ranging from 2.0MM-8.0MM. Blunt sur...Read more -
Thermal expanded seamless steel pipe details
Thermal expansion seamless steel pipe is what we often call thermal expansion pipe. Steel pipes with relatively low density but strong shrinkage (seamless steel pipe) can be referred to as thermal expansion pipes. A rough pipe finishing process that uses cross-rolling or drawing to enlarge the di...Read more -
What is an ERW steel pipe
What is an ERW steel pipe? The biggest difference between ERW steel pipe (Electric Resistance Welding, abbreviated as ERW) and seamless steel pipe is that ERW has a weld seam, which is also the key to the quality of ERW steel pipe. Modern ERW steel pipe production technology and equipment, due to...Read more -

Applications of welded steel pipes
Welded pipes are made of steel plates or steel strips that are bent and then welded. According to the welding seam form, it is divided into straight seam welded pipe and spiral welded pipe. According to the purpose, they are divided into generally welded pipes, galvanized welded pipes, oxygen-blo...Read more
